-Entanglement Measure for Multipartite Systems without Convex-Roof Extensions and its Evaluation
Jie Guo, Shuyuan Yang, Jinchuan Hou +2
Multipartite entanglement underpins quantum technologies but its study is limited by the lack of universal measures, unified frameworks, and the intractability of convex-roof exten…
Detecting -nonseparability and -partite Entanglement with Generalized Skew Information and Mutually Unbiased Measurements
Xiaofei Qi, Yuyang Pang, Jinchuan Hou
Multipartite quantum entanglement, as a core quantum resource, is fundamental to the advancement of quantum science and technology. In multipartite quantum systems, there are two k…
Multipartite correlation measures and framework for multipartite quantum resources theory
Taotao Yan, Jinchuan Hou, Xiaofei Qi +1
In recent years, it has been recognized that properties of multipartite physical systems, such as genuine multipartite entanglement, can be considered as important resources for qu…
Witnessing nonlocality in quantum network of continuous-variable systems by generalized quasiprobability functions
Taotao Yan, Jinchuan Hou, Xiaofei Qi +1
Gaussian measurements can not be used to witness nonlocality in Gaussian states as well as the network nonlocality in networks of continuous-variable (CV) systems. Thus special non…
An easily computable measure of Gaussian quantum imaginarity
Ting Zhang, Jinchuan Hou, Xiaofei Qi
The resource-theoretic frameworks for quantum imaginarity have been developed in recent years. Within these frameworks, many imaginarity measures for finite-dimensional systems hav…
Gaussian unsteerable channels and computable quantifications of Gaussian steering
Taotao Yan, Jie Guo, Jinchuan Hou +2
The current quantum resource theory for Gaussian steering for continuous-variable systems is flawed and incomplete. Its primary shortcoming stems from an inadequate comprehension o…
